Still recovering from the loss of his wife, the police forensics expert and secret serial killer (Michael C. Hall) is on the trail of not one murderer but two (Colin Hanks and Edward James Olmos, as a lethal duo with a symbiotic relationship) in this round of the Showtime series.

Debra (Jennifer Carpenter) has challenges settling into her new authority in the Miami Police Department, and also in the surprising thoughts she begins having about Dexter. Mos Def and Molly Parker ("The Firm") also guest star. *** (Not rated: AS, P, GV) (Also on Blu-ray)
